Answer:
-1 and 9
Step-by-step explanation:
To solve the quadratic, factor and set its factors equal to 0. Factoring is the action of breaking up a polynomial into pieces which multiply to make it. The factors are found by multiplying numbers to make C and add to B of .
Here c = -9 and b = -8. The numbers -9 and 1 multiply to -9 and add to -8. These are the factors (x-9)(x+1).
Set each equal to 0 and solve for x.
x-9 = 0
x = 9
x+1 =0
x = -1
Answer:
Step-by-step explanation:
Given that a convenience store regularly buys mangoes from a wholesale dealer. For every shipment, the manager randomly inspects five mangoes from a box containing 20 mangoes for damages due to transportation. Suppose the chosen box contains exactly 2 damaged mangoes.
In the selected box 18 good mangoes and 2 damaged mangoes are there
a) Find the probability that the first mango is not damaged.
= prob of selecting 1 from any one of 18 good mangoes =
b. Find the probability that neither of the mangoes is damaged. =
Prob of selecting 2 from 18 good mangoes
=
c. Find the probability that both mangoes are damaged.
= Prob of selecting 2 from 2 bad mangoes
=
Answer:
Step-by-step explanation:
using the slope-intercept formula, u have this so far as an equation (just knowing the slope):
To find the y-intercept, substitute in the values of the coordinates given to solve for b:
so u can just put 8 into your slope-intercept formula () and that's it! hope this helps!
